2305A-1HDCGI8

Overview

The Renesas 2305A-1HDCGI8 is a zero-delay buffer integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 3.6V and supports maximum frequencies up to 133MHz. The device features one LVTTL input and five CMOS/LVCMOS/TTL outputs, packaged in an 8-SOIC (0.154" width) surface-mount package. It is designed for industrial temperature ranges from -40°C to +85°C and complies with RoHS3 standards.

Feature Summary

• Zero-delay buffer architecture with on-chip PLL feedback
• 1:5 input-to-output ratio supporting frequencies up to 133MHz
• Low skew output capability (<250 ps)
• Industrial temperature rating (-40°C to +85°C)

Applications

• Clock distribution in high-speed digital systems
• Buffering reference clocks for processors or memory interfaces
• Low-skew clock generation in industrial equipment

Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) versus commercial variants. Confirm the '8' suffix indicates tape-and-reel packaging (3,000 units) rather than cut-tape or tube formats. Cross-reference the manufacturer part number with distributor codes such as 800-1268-2-ND to ensure correct component revision and lead-free status compliance.

Selection Notes

Select this component when a single-ended LVTTL input must be buffered into five low-skew CMOS outputs without external phase-locked loop components. Ensure the system requires the industrial temperature grade (-40°C to +85°C). Verify that the 8-SOIC package dimensions fit the PCB layout constraints and that the 3.3V nominal supply voltage aligns with the target logic levels.

Part Context

This part belongs to the IDT 2305 family of zero-delay buffers, now produced under the Renesas brand following acquisition. The base model 2305-1 provides standard drive, while the -1H variant offers higher drive strength. The 2305A series represents an updated iteration with optimized performance characteristics for modern clock distribution networks.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct pin-compatible alternatives only after consulting official Renesas cross-reference guides.
